    Object that contains message ksb.csle.common.proto.StreamDidentProto.RoundingInfo RoundingInfo contains attributes as follows:

    • selectedColumnId: Column ID to apply the rounding function
    • roundStep: the step of round (ex., teenage for age)
    • method: how to round the given data
    • fieldInfo: the info about column attributes (identifier, sensitive, ..)
    • check: the method how to verify the performance of anonymized data
